In
this talk I will propose and analyze a nanoengineered vortex array in
a thin-film type-II superconductor as a magnetic lattice for
ultracold atoms. This proposal addresses several of the key questions
in the development of atomic quantum simulators. By trapping atoms
close to the surface, tools of nanofabrication and structuring of
lattices on the scale of few tens of nanometers become available with
a corresponding benefit in energy scales and temperature
requirements. This can be combined with the possibility of magnetic
single site addressing and manipulation together with a favorable
scaling of superconducting surface-induced decoherence.
